Description

  The present invention relates to a detachable duct used in a server room.

  Conventionally, an air conditioner is installed in a server room that accommodates a plurality of servers so that the servers are not overheated due to heat generated by the servers. The air conditioner performs air circulation cooling in which indoor air in the server room is sucked from the ceiling, the sucked air is cooled, and the cooled air is exhausted from the floor. As a result, the temperature in the server room is appropriately maintained, and the inside of the server is not easily overheated.

  However, the thermal load on each server can vary greatly throughout the year or throughout the day. In addition, new servers are installed in the server room, and old servers are removed. Furthermore, a new installation is installed inside the server room, or the installation that has been installed is removed. For this reason, the heat source of the server room fluctuates, and the air flow inside the server room also changes, so the cooling efficiency by air circulation cooling decreases, and in some cases inside the server room, An area (hot spot) where the density of heat generation is locally high may occur.

  In such a case, the server administrator needs to adjust the amount, direction, and temperature of the air blow, but it has been difficult to cope with local heat generation in the conventional air conditioner.

  Therefore, a technique is known in which a ceiling mounting duct is suspended along the ceiling and the hot spot air is sucked through the ceiling mounting duct (see, for example, Patent Document 1). . The under-ceiling mounting duct is attached with a plurality of bolts and nuts such that the intake opening of the under-ceiling mounting duct is installed above the hot spot.

JP 2008-051475 A

  Normally, when a hot spot exists in the server room, the server sucks air in the hot spot, and the server is overheated, which easily triggers a hardware trouble or the like. Therefore, the server administrator tries to quickly remove the hot spot.

  However, the under-ceiling mounting duct described in Patent Document 1 is suspended along the ceiling of the server room. For this reason, when a server other than the server that generates heat frequently generates heat, first remove the duct for installation below the ceiling, which is installed along the ceiling, and then start new heat generation. It is necessary to re-install the removed ceiling mounting duct on the upper side of the server rack where the installed server is installed.

  Therefore, in the under-ceiling mounting duct described in Patent Document 1, it is difficult to relocate, and a hot spot generated inside the server room cannot be easily eliminated.

  An object of the present invention is to provide a detachable duct that can be easily installed at a position where a hot spot generated inside a server room can be easily eliminated.

  The present invention relates to a detachable duct that is provided in a server room and is detachably attached to a plurality of air intake openings for air intake of an air conditioner that adjusts the air temperature in the server room. The detachable duct according to the present invention includes a connecting portion that is detachably connected to one or more intake openings of the plurality of intake openings, and a cylindrical duct main body having flexibility. One opening of the duct main body is disposed in the vicinity of the one or more intake openings by the connecting portion. The other opening of the duct main body is directed to the vicinity of the air heated by at least one of the plurality of servers in the server room.

  The detachable duct according to the present invention preferably further includes a thermometer attached to the other opening of the duct main body or in the vicinity thereof.

  It is preferable that the connection portion is configured to be detachably connected to the one or more intake openings so as to cover a part of the area of the one or more intake openings.

  It is preferable that the cross-sectional area of the inner diameter of the duct main body portion decreases as it goes from the one opening to the other opening.

  It is preferable that the connecting portion is configured to be displaceably connected to the one or more intake openings.

  It is preferable that the duct main body is formed of a material capable of storing a shape.

  It is preferable that the duct main body portion is formed of a non-combustible material or a flame retardant material.

  It is preferable that the connecting portion has a sandwiching portion that sandwiches the one or more intake openings, and the sandwiching portion has a slip stopper at a portion that sandwiches the one or more intake openings.

  It is preferable that the surface of the duct main body is formed of a material whose color changes according to the ambient temperature outside the duct main body.

  The detachable duct according to the present invention further includes a blower with a built-in power supply, and the blower has air inside the duct main body portion from the other opening of the duct main body portion to one opening of the duct main body portion. It is preferable that it is attached to the said duct main-body part so that it may flow.

  According to the present invention, it is possible to easily install a detachable duct at a position where a hot spot generated inside the server room can be easily eliminated.

It is a perspective view of the installation / removal duct according to the present invention. It is explanatory drawing which shows the state which applied the attachment / detachment duct shown in FIG. 1 to the server room.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
In the present embodiment, the case where the detachable duct of the present invention is used in a server room is described as an example. However, it can also be used in a computer room in which network devices and the like are installed in addition to the server.

  As shown in FIG. 1, the detachable duct 100 according to the present invention is detachably attached to a plurality of intake openings 310 provided in the server room 300 shown in FIG.

  As shown in FIG. 1, the detachable duct 100 includes a connecting portion 110 that is detachably attached to any of the plurality of intake openings 310, and a cylindrical duct body portion 105 that is connected to the connecting portion 110 and has flexibility. With. The duct main body part 105 includes a rectangular connection part 120 connected to the connection part 110 and a hollow bellows part 130 connected to the connection part 120 in an airtight manner.

  The connecting portion 110 is formed at a clip-shaped sandwiching portion 118 that sandwiches the frame portion, the mesh portion, the lattice portion, and the like of the intake opening 310, a support portion 112 that supports the sandwiching portion 118, and the tip of the sandwiching portion 118. The anti-slip part 116 is provided. In the present embodiment, the number of connecting portions 110 is described as four, but is not limited thereto.

The sandwiching portion 118 is formed of an elastic body. The sandwiching portion 118 is elastically deformed so that the pair of tips of the sandwiching portion 118 are always pressed against each other. The sandwiching portion 118 has a non-slip portion 116 at a portion sandwiching the intake opening 310. Therefore, the sandwiching portion 118 is configured so that the intake opening 310 can be sandwiched so that one opening 122 of the connecting portion 120 is disposed in the vicinity of the intake opening 310.
In the detachable duct 100 provided with the connecting portion 110 as described above, since the detachable duct 100 can be easily installed on the ceiling 302, a large-scale construction work in the server room 300 becomes unnecessary.

  The connecting portion 120 has a cylindrical shape that forms a hollow portion 121, and a rail portion 124 that guides the support portion 112 so as to be linearly movable along a side around the one opening 122 is formed in one opening 122 thereof. Prepare. Since one opening 122 is rectangular, the rail part 124 is also formed in a rectangular shape. Therefore, the rail portion 124 has a pair of portions that face each other with the one opening 122 interposed therebetween. Thereby, the connection part 120 is comprised with respect to the intake opening part 310 so that it can displace in a horizontal direction. One opening 122 of the connecting portion 120 is formed to have a size so as to cover the entire intake opening 310 or a part of its area. One opening 132 of the bellows part 130 is airtightly connected to the other opening 123 of the connection part 120.

  The bellows portion 130 is formed so that the cross-sectional area of the inner diameter of the bellows portion 130 decreases from one opening 132 toward the other opening 134. The bellows part 130 forms a bellows shape with a material capable of storing the shape. The bellows portion 130 is formed of, for example, a non-combustible material or a flame retardant material. The surface of the bellows portion 130 is formed of a material whose color changes according to the temperature around the outside of the bellows portion 130. For example, the bellows portion 130 has such a length that the other opening 134 can be directed to the vicinity of the hot spot HP generated inside the server chamber 300 in a state where the pinching portion 118 holds the intake opening portion 310.

  The detachable duct 100 includes a thermometer 136. The thermometer 136 is attached to the other opening 132 of the bellows part 130 or the vicinity thereof, for example, so as to measure the temperature of the air in the vicinity of the other opening 132.

  The detachable duct 100 includes a blower 138 with a built-in power source. The blower 138 is attached to the duct body 105 so that the air inside the duct body 105 flows from the other opening 134 to the one opening 122. As a result, the air inside the duct main body 105 is forced to flow from the other opening 134 to the one opening 122. That is, the detachable duct 100 sucks air in the vicinity of the other opening 134 more strongly, coupled with suction by the air conditioner 400. That is, by configuring the cross-sectional area of the bellows portion 130 as described above, the synergistic effect with the suction force by the air conditioner 400 can be enhanced, and hot spots can be more efficiently eliminated.

  As shown in FIG. 2, the above-described detachable duct 100 is used to suck in air from the hot spot HP in the server room 300.

  As shown in FIG. 2, a plurality of server racks 200 are accommodated in the server room 300. The plurality of server racks 200 are divided into a plurality of server rack groups 210 so that each constitutes a row of the plurality of server racks 200. Each server rack group 210 is arranged in an aligned state such that the front surface 201 and the back surface 202 of the plurality of server racks 200 are on the same side. Each server rack 200 accommodates a plurality of servers 205.

  Each server 205 is a so-called blade type server. Since the blade type server 205 generally generates a large amount of heat, the blade type server 205 is provided with a cooling fan having a strong intake power. The cooling fan provided in the blade type server 205 allows air to flow from the front surface 201 to the rear surface 202 of the server rack 200 when the server 205 is accommodated in the server rack 200. The server 205 is provided. Therefore, air heated by the server 205 flows from the front surface 201 to the rear surface 202 of the server rack 200.

  The plurality of server rack groups 210 are arranged on the floor 304 of the server room 300 so that the front surface 201 or the back surface 202 of the server racks 200 of the two adjacent server rack groups 210 face each other. The space 311 is called a cold aisle (cold air passage), and the space 312 is a hot aisle (warm air passage). The air in the space 311 where the front surfaces 201 of the server racks 200 of two adjacent server rack groups 210 face each other (depending on the type of server, it is generally preferable to be in the range of 20 ° C. to 25 ° C.). It is sucked in by the cooling fan of the server 205. Further, air heated by the server 205 (generally air of about 30 ° C.) is discharged into a space 312 where the rear surfaces 202 of the server racks 200 of two adjacent server rack groups 210 face each other.

  The server room 300 has a plurality of intake openings 310 in the ceiling 302 above the space 312. An intake duct 303 is provided on the upper side (back side) of the ceiling 302 of the server room 300. The intake duct 303 is airtightly connected to a plurality of intake openings 310 provided in the ceiling 302. Further, the end of the intake duct 303 is airtightly connected to the intake port of the air conditioner 400. Therefore, when the air conditioner 400 is activated, the air inside the server room 300 is sucked into the air intake port of the air conditioner 400 through the plurality of air intake openings 310 and the air intake duct 303.

  The air conditioner 400 cools the air sucked from the intake port to a predetermined temperature (for example, about 16 ° C. to about 20 ° C.), and sends the cooled air from the exhaust port. The air sucked from the intake port is usually warm air.

  The air outlet 400 is airtightly connected to an exhaust duct 314 disposed under the floor 304. The air cooled by the air conditioner 400 is sent into the server room 300 from the exhaust opening 320 through the exhaust duct 314. Since there is a space 311 where the front surface 201 of the server rack 200 faces on the upper side of the exhaust opening 320, the cooled air is sent into the server 205 by the cooling fan provided in the server 205. The server 205 is cooled by the generated air.

  Since the server rack 200 includes a space where the server 205 is not disposed and a space between adjacent servers 205, the heated air discharged into the space 312 passes through the space of the server rack 200 again. , May return to space 311. With such air circulation, the air may be heated to become a hot spot HP (air having a temperature of about 28 ° C. or higher).

  When the server administrator feels that there is such a hot spot HP, the server administrator removes such a hot spot HP as follows.

First, the server administrator searches for the intake opening 310 in the vicinity of the place where the hot spot HP is felt among the plurality of intake openings 310 installed on the ceiling 302.
Next, the server administrator sandwiches the clip-shaped sandwiching portion 118 of the connecting portion 110 between the frame portion, the mesh portion, the lattice portion, and the like of the intake opening 310. At this time, one opening 122 is disposed in the vicinity of the intake opening 310. For this reason, since the air inside the server room 300 is sucked from the intake opening 310, the air inside the bellows part 130 is also sucked through the intake opening 310 and the hollow part 121 of the connection part 120. Become so.

  Next, since the server administrator is constituted by the bellows portion 130 elastic body, the opening direction of the other opening 134 and the installation position are adjusted. Since the air in the hot spot HP is hot air, the server administrator cannot visually check the air. However, the server administrator points the other opening 134 in such a direction as to efficiently suck the air in the hot spot based on the temperature indicated by the thermometer 136 provided in the detachable duct 100. Can do.

  Further, since the surface of the bellows portion 130 is formed of a material whose color changes in accordance with the temperature around the outside of the bellows portion 130, the server administrator can determine not only the temperature near the other opening 134, The temperature of the air between one opening 132 and the other opening 134 can be grasped. For this reason, the other opening 134 can be directed in such a direction that the air in the hot spot can be sucked more efficiently.

  In addition, since the bellows portion 130 is formed of a material capable of storing a shape and has a bellows shape, the orientation of the other opening 134 changed by the server administrator is maintained by the material capable of storing the shape.

  When the server administrator attaches the detachable duct 100 to the intake opening 310, the air inside the bellows part 130 flows into the intake opening 310 due to the suction of air in the intake opening 310, and near the other opening 132. The air in the air is sucked into the bellows part 130. At this time, hot air in a hot spot flows inside the bellows portion 130. However, since the bellows portion 130 is formed of a non-combustible material or a flame retardant material, the bellows portion 130 can withstand the state in which hot air flows inside, and is also in accordance with disaster prevention standards normally applied to server rooms. Is easy to fit.

  Further, the bellows portion 130 is formed so that the cross-sectional area of the inner diameter of the bellows portion 130 decreases from the one opening 132 toward the other opening 134, so that the other opening 134 moves toward the one opening 132. The flow rate of air increases as it goes from one opening 132 to the other opening 134. That is, in the vicinity of the other opening 134, the air suction speed is high, and thus a wide range of air in the other opening 134 is sucked into the bellows part 130.

  As described above, the server administrator can easily install the detachable duct at a position where the hot spot HP generated inside the server room 300 can be easily eliminated.

  In the above embodiment, the case where the detachable duct 100 is used in the server room 300 has been described as an example. However, the present invention is not limited to this, and can be used in a computer room in which network devices and the like other than the server 205 are installed. It is.

  Although the detachable duct 100 has been described as being detachably connected to one intake opening 310 of the plurality of intake openings 310, the present invention is not limited thereto, and two or more intakes of the plurality of intake openings 310 are not limited thereto. You may make it connect to the opening part 310 so that removal is possible. That is, the detachable duct 100 may be configured to take in air in the vicinity of the other opening 134 by using the intake force of two or more intake openings 310.

  As mentioned above, although demonstrated using embodiment of this invention, the technical scope of this invention is not limited to the range as described in the said embodiment. Various modifications or improvements can be added to the above embodiment. It is apparent from the description of the scope of claims that the embodiments added with such changes or improvements can also be included in the technical scope of the present invention.
